Conjunctivitis (“Pink Eye”)
What is conjunctivitis?
Conjunctivitis is an inflammation (swelling) of the
conjunctiva – the thin layer that lines the inside of
the eyelid and covers the white part of the eye. It is
often called “pink eye” because it can cause the
white of the eye to become pink or red.
What causes conjunctivitis?
Conjunctivitis is most commonly caused by viruses,
bacteria, or allergens. It can also be caused by
chemicals, fungi, contact lens use, and certain
diseases.
What are the signs and symptoms?
• Pinkness or redness of the white part of the
eye(s) – often one eye if bacterial; both eyes if
viral or allergic)
• Eye discharge:
o Thick; white or yellow – more common for
bacterial conjunctivitis
o Watery and clear – more common for viral
or allergic conjunctivitis
• Itching, pain, irritation, or burning
• Crusting of eyelids or lashes, particularly in the
morning
When to seek medical care:
• Moderate to severe eye pain or intense redness
• Vision problems, such as sensitivity to light or
blurred vision, that persist
• Symptoms occur in a person with a weakened
immune system (HIV infection, cancer
treatment)
How is conjunctivitis diagnosed?
Your healthcare provider can usually diagnose
conjunctivitis based on your symptoms and recent
history. She may collect a swab of the discharge
from your eye(s) for laboratory testing.
How is conjunctivitis treated?
Artificial tears and cold compresses may be used to
relieve dryness and swelling. Medications and
other treatments depend on the cause:
• Viral:
o Often clears up on its own after 7-14 days
o Your healthcare provider may prescribe
antiviral medication if necessary
• Bacterial:
o Your healthcare provider may prescribe
antibiotic eye drops or ointment
o Infection should clear within several days
• Allergic:
o Allergy medication and certain eye drops
(topical antihistamines and
vasoconstrictors) can provide relief of
symptoms
Prevent the spread of conjunctivitis:
• Allergic conjunctivitis is not contagious;
however, viral or bacterial conjunctivitis is
easily spread person to person
• Avoid rubbing or touching your eyes. Use a
tissue to wipe away drainage, throw it away and
wash your hands afterwards
• Clean your hands often with soap and water
• Avoid sharing make-up, eye drops, towels, and
pillows.
